What do you remember
from last week's lesson?

How many different types of plates are there?

1. 1
2. 2
3. 3
4. 4

Take notes

two types of plates

1. Continental plate:  Plate that consists of a large land surface.

2. Oceanic plate: Plate that consists of a large sea surface.

Click on the map, write down one example of each type of plate.

Subduction forms volcanoes

Subduction: When the heavy oceanic plate, dives under the light continental plate. 

*Subduction happens when a continental and oceanic plate are in a convergent movement. 

Earthquakes are cause by...

1. Convergent movement/Subduction

2. Transform movement

* The movement of the plates is not smooth, a lot of tension (spanning) is built up between the plates. When the pressure (druk) is too high, the plates snap loose (schieten los) which creates the shock. 

Take a look at figure 1 + 3 on page 104 + 105 in your coursebook.
Why do you think Japan has so many volcanoes and earthquakes?
